Abstract

A composite that includes a layered MXene comprising at least two layers, and an amount of a chalcogen confined between the at least two layers. An electrode that includes a composite that includes a layered MXene comprising at least two layers, and an amount of a chalcogen confined between the at least two layers. Power cells that include the composite. A method, comprising: with an intercalant spacer, effecting an increase in an interlayer spacing in a multilayered MXene composition; and effecting intercalation of a chalcogen into the interlayer spacing so as to confine the chalcogen between layers of the multilayered MXene composition, and optionally effecting removal of the intercalant spacer.
